Summary:
The Swift REPL lets you use inout parameters to change the value of a let-declared constant.
Steps to Reproduce:
Enter the following in the Swift REPL:
func testIncrement(inout b: Int) {
b += 5
}
let x = 4
testIncrement(&x)
x
Actual Result:
x = 9
Expected Result:
Error. x should not be allowed to be modified because it should be a constant. In order for this code to run, x should have to be declared using “var.”
